Subject Re: Time series data model and tombstones

Your partitioning key is text. If you have multiple entries per id you are
likely hitting older cells that have expired. Descending only affects how
the data is stored on disk, if you have to read the whole partition to find
whichever time you are querying for you could potentially hit tombstones in
other SSTables that contain the same "id". As mentioned previously, you
need to add a time bucket to your partitioning key and definitely use
DTCS/TWCS.
